Ubuchwepheshe be-antenna "bungumkhawulo ophezulu" wokuthuthukiswa kwesistimu

Namuhla, uThisha ohlonishwayo u-Chen wase-Tianya Lunxian uthe, “Ubuchwepheshe be-antenna buwumkhawulo ophezulu wokuthuthukiswa kwesistimu.Ngenxa yokuthi ngingathathwa njengomuntu othi, angikwazanga ukuzibamba kodwa ngacabanga ukuthi ngingawuqonda kanjani lo musho nokuthi ukuqonda okuhlukile kuzowuthinta kanjani umsebenzi wami wesikhathi esizayo.

Uma ubuchwepheshe be-antenna buthathwa njengomkhawulo ophezulu wokuthuthukiswa kwesistimu, ukuqonda kwami ​​​​kwasekuqaleni ukuthi izinti ziyingxenye ebalulekile yezinhlelo zokuxhumana ezingenazintambo.Ziyimishini yokudlulisela nokwamukela yamaza kagesi, futhi kungakhathaliseki ukuthi imishini yokuxhumana ephathwa ngesandla, amanethiwekhi angenantambo, noma ukuxhumana ngesathelayithi, azikwazi ukwenza ngaphandle kwezimpondo.

Ngokombono wokusebenza kahle kokudluliselwa kwe-antenna, ukwakheka nokusebenza kwe-antenna kuthinta ngqo ukusebenza kahle kokudluliselwa kwesignali.Uma idizayini ye-antenna ingalungile (okuhlanganisa indawo ye-antenna, isiqondiso se-antenna, ukuzuza kwe-antenna, ukufaniswa kwe-antenna, indlela ye-antenna polarization, njll.), ngisho noma ezinye izingxenye (njengama-amplifiers, modulators, njll.) zisebenza kahle, azikwazi ukuzuza ukusebenza kahle okuphezulu.

Ngokombono wekhwalithi yokwamukela i-antenna, ikhono lokwamukela i-antenna liphinde linqume ikhwalithi yesignali yesiphetho sokwamukela.Ukwemukelwa okungekuhle kwe-antenna kungaholela ekulahlekelweni kwesignali, ukuphazamiseka, nezinye izinkinga.

Ngokombono womthamo wesistimu, ezinhlelweni zokuxhumana ezingenazintambo, ukwakheka kwezinti nakho kuthinta umthamo wesistimu.Isibonelo, ngokusebenzisa ama-antenna ayinkimbinkimbi kakhulu, umthamo wesistimu ungandiswa futhi izixhumanisi zokuxhumana ezihambisanayo zinganikezwa.

Ngokombono wokusetshenziswa kwendawo, ukuthuthukiswa kobuchwepheshe be-antenna, njenge-beamforming kanye ne-MIMO (MultipleOkokufaka Okuningi Okuphumayo), kungasebenzisa izinsiza zesikhala ngokuphumelelayo futhi kuthuthukise ukusetshenziswa kwe-spectrum.

Ngokucatshangelwa okungenhla, ukuthuthukiswa kanye nokwenza kahle kobuchwepheshe be-antenna kube nomthelela omkhulu ekusebenzeni nasekuthuthukisweni kwezinhlelo zokuxhumana ezingenazintambo.Kungashiwo ukuthi "kuwumkhawulo ongaphezulu" wokuthuthukiswa kwesistimu, okungibonisa ukuqhubeka kwemboni ye-antenna kanye nesidingo sokuqhubeka nokuqhubekela phambili.Kodwa lokhu kungase kungasho ukuthi inqobo nje uma ubuchwepheshe be-antenna buyathuthukiswa, ukusebenza kwesistimu kungathuthukiswa ngokungenamkhawulo, njengoba ukusebenza kwesistimu kuphinde kuthintwa ezinye izici eziningi (njengezimo zesiteshi, ukusebenza kwehadiwe, ubuchwepheshe bokucubungula isignali, njll.), kanye nalezi zici eziningi. izici nazo zidinga ukuthuthukiswa ngokuqhubekayo ukuze kwenziwe uhlelo lusebenze kahle futhi luthembeke.

Lindela intuthuko nenqubekela phambili kubuchwepheshe be-antenna nezinye izici, njengobuchwepheshe be-antenna ehlakaniphile, ubuchwepheshe obuhlanganisiwe be-antenna, ubuchwepheshe be-antenna ye-photonic, ubuchwepheshe be-antenna obulungisekayo, ubuchwepheshe be-antenna array/MIMO/millimeter wave, ubuchwepheshe be-antenna metamaterial, njll., ukuphromotha ngokuqhubekayo ukuthuthukiswa kobuchwepheshe be-antenna futhi wenze i-wireless ibe mahhala!
